Two-Port 40 Gbps Network Adapter
The Mellanox CX354A ConnectX-3 is a dual-port QSFP+ InfiniBand adapter built for high-performance computing clusters. It delivers up to 40 Gbps per port using Quad Data Rate technology. This card targets system integrators and data-centre operators who need low-latency fabric for scientific workloads or high-frequency trading platforms.
QSFP+ Interface Flexibility
Each of the two ports accepts standard QSFP+ transceivers so you can choose multi-mode or single-mode fibre to match the link distance. The adapter ships without optics or cables; those must be sourced separately to suit the specific rack layout. No software licences or management utilities are bundled in the box.
Standard PCIe Installation
The card installs in a standard PCI Express slot and is recognised by common Linux and Windows drivers without extra configuration. The main friction point is sourcing compatible QSFP+ modules and fibre patch cords that match the required reach and fibre type. Buyers who need copper twinax or Ethernet protocol support should verify interoperability before purchase.

Spørsmål om denne varen
Will the QSFP+ transceivers on this CX354A need periodic replacement?
The CX354A uses standard QSFP+ modules that can be swapped individually if a link degrades; the card itself has no user-serviceable parts.
What limits sustained 40 Gbps throughput on this adapter?
Sustained line-rate traffic is bounded by the PCIe bus width and host CPU offload capacity rather than the dual-port 40 Gbps InfiniBand links.
How much heat and power does the CX354A produce under continuous load?
The adapter draws power from the PCIe slot and relies on system airflow; no onboard fan is present, so case cooling determines operating temperature.
